Steps to reproduce:

Expected results:

Should not crash? Chrome handles the webpage fine, it doesn't load but you can close the webpage without a crash.

No crash here, just Firefox hangs and still sucks all available RAM.

Post some URLs of these crashlog reports from about:crashes

No crashlog is produced. I left it for a while and I got this - https://i.gyazo.com/453dab83f9a9ccccdd63f723f916c52a.png

Looks like the following script causes the issue - https://tsgess.com/lawson/portal/objects/PortalConfig.js

The offending URL crashed Firefox 46.0.1 Win32 for me after a few minutes. Unfortunately, the crash reporter did not produce a crash report.

This looks to me like it is due to loading a synchronous script. Either way I can only see that it makes the tab slow. I wasn't able to reproduce it taking all my ram or crashing.
What OS are people using here?
